Th <feComponentTransfer> SVG filter primitive performs color-component-wise remapping of data for each pixel. It allows operations like brightness adjustment, contrast adjustment, color balance or thresholding.

The calculations are performed on non-premultiplied color values. The colors are modified by changing each channel (R, G, B, and A) to the result of what the children <feFuncR>, <feFuncB>, <feFuncG>, and <feFuncA> return.
